To all whom it may] concern: 1 I

lie it 'linownfthat LGiiOliGn W. BLAKE, a

citizen of the United siding at it 'andot t'e, in the county of lVayne and State of -Miehigan, have invented 'cer-' tain new and useful Improvements in Carr Filling Machines, of which the following is a specificatien. reference being had therein to the accompanying drawings.

This invention relates to an automatic filling machine, and has special reference a)! :1 machine for filling cans cartons, contain-- ers or receptacles with granular, pulverized or loose 'I'Hfit't'Sl, for instance, sugar, salt etc. The machine may also'handle liquids.

molasses, and any free flowing fluid.

My ii'ivention aims 'to provide a rotarv filling u'iaehine wherein positive and'reliable means are employed, in a manner as here- 121: er set forth, forautomatically and su'c c vel'y filling receptacles placed in the machine with a predeterminedipiantity of matterihat is automatically weighed with preeision so that the receptacles areuniformly filled without shortage overweight, or waste of niatterpoured in or-ouirof the receptacle. The continuous andiminterrupted tilling of receptacles in the machine necessitates means for supplying the machine with empty receptacles and the removal of filled recepi'ac s, and this is accomplished byan automatic loading and unloading device f0 a rotary receptacle carrier of the machine.

Mv invention further aims to provide a rotary filling machine 'for various kinds of recepta :les embodying a mainreservoir and an aui'lia'ry reservoir for matter that is to he placed in the receptacles. Provision made for aiitoinatieally controlling the supply of matter from the main reservoir to the auxiliary reservoir and novel electrically operated feed shut off devices control the discharge of matter froin tl e auxiliary reservoir. v

M invention still furthenaims to provide a filling niachincjof the above type including pneumatic vibrators for the auxiliary reservoir of the machine and filling spouts thereof, and. these pneumatic vibrators together witliother novel instrumentalities a ll coiiperate to insure safe, expeditious and echmnienl filling of receptacles; the unach piiringno'other attention than that .ing and stopping the same.

The principal parts of my iachine, namely, a main frame, power and driven States of America, r'e- I trical shafts; main and auxiliary feed reservoirs with automatic controllingdevices between the reservoirs; electrically operated feed shut ofi device's for the auxiliary reservoir; pneumatic vibrators for the auxiliary reservoir and valve controlling the operation of the vibrators; rotary carrier and scale platforms; power distributor for the elecdeviees of the machineyand an auto matic loading and unloading device for the rotary carrier,-'will gether with tliefnovel arrangeiinent and ohje'cts accomplished fromsucl'i amcoinbination of parts.

In describing my invention by aid of the views above referred to, I desire to point out that the same are merely illustrative of the automatic receptacle filling machine as now being constructed by me, and I do not care to confine myself to the precise construction and arrangement of parts shown. The following description is therefore to be broadly construed as including such substitute constructions and arrangement of parts as are the obvious equivalent of those to be here-' inafter referred to under separate captions. Main frame, power and driven shafts. (Figs. 1, 2 and ff.)

The reference numeral 1 denotes a suitable base or foundation and rigidly'connected thereto, as at 2, are a plurality of uprights or columns 3, 4:, 5 and 6, the uprights 4, 5 and 6 being of the same height and having the upper ends thereof connected by a threearm spider T provided with a central vertical bearing 8. The upright 3 is of less height than the uprights &. 5 and 6 and cooperates with the uprights i and 6 in supporting a horizontal platform 9 at what may be considered the front side of the machine, said platform constituting a support for the automatic loading and unloading device of the machine.

The base 1 is provided with a central socket 10 and an end thrust bearing 11 for a vertical drive shaft 12 which has the upper edge thereof journaled in the bearing 8 of the spider 7. Fixed on the drive shaft 12, above the base 1, is a worm wheel 13 engaging with a worm 1 1 on the armature shaft 15 of an electric motor 16, the motor being operated from a suitable source of electrical energy and constituting power of a convenient form for operating the filling machine- Main and auxiliary reservoirs with automatic feed controlling de'vzce between the reservoirs.

(Figs. 1, 2, 3 and 6.)

spout 18 connected to a circular cover plate 19 attached to the bottom side of the spider 7, said cover having an opening in communication with the discharge spout 18 of the main reservoir.

The drive shaft 12 is provided with a fixed collar 20 and suitably connected thereto is a circular bottom plate 21 for an annular auxiliary reservoir 22 composed of inner and outer annular walls, as best shown in Figs. 1 and 6. The annular reservoir 22 is rotatable with the drive shaft 12 and the upper edges of the reservoir are free to move beneath the cover 19, which excludes dust and foreign matter from the auxiliary reservoir. The auxiliary reservoir is constantly in communication with the discharge spout 18 of the main reservoir 17. To control the supply of matter to the auxiliary reservoir 22, the discharge spout 18 of the main reservoir 17 is provided with a gate slidable in a guide member 24 carried by the discharge spout 18. The gate 23 is opened and closed by a slotted crank 25 articulated with the gate and carried by a rock shaft 26 journaled in bearings 27 and 28 on the spout 18 and the cover 19 respectively. As shown in Fig. 2. the main reservoir 17 is preferably located at the front side of the auxiliary reservoir 2;, and the rock shaft 26 extends rcarwardly across the cover 19 to a segment shaped slot 29 in said cover. On the end of the rock shaft 26 is fixed a curved drag or float arm 30 extending through the slot 29 into the auxiliary reservoir 22, to be raised and lowered by dragging over the surface of the matter deposited in the auxiliary reservoir from the main reservoir. The end of the arm 30 is flattened for this purpose and as the level of the matter within the auxiliary reservoir is raised therein, the

arm 30 is gradually raised to impart a rocking movement to the shaft 26 and gradually close the gate In this matter the supply of material to the auxiliary reservoir 22 is automatically controlled, and to prevent the material or matter in the auxiliary reservoir from unduly eaking, packing down or solidifying, the cover 19 is provided with a de pending agitator 30, preferably in the form of a revoluble star revolve and agitate the matter within the auxiliary reservoir, when said reservoir is revolved by the drive shaft 12. The bottom plate 21 of the auxiliary reservoir 22 is provided with a plurality of circuinferentially disposed and equally spaced discharge nipples 31, preferably six in number for this particular size of machine. Suitably conneeted to the nipples 31 are depending flexible and tubular discharge spouts 32 having the lower ends thereof suitably connected to discharge nozzles 33, carried by a circular plate 34 mounted on a collar 35 attached to the drive shaft 12. The nozzles 33 are fitted with pivoted horizontal manuwheel that is caused to 115 ally operated shutters 36 so that the dis charge nozzles can be closed, particularly Electrically operated feed shut-077' devices for the (auxiliary reservoir.

(Figs. 1, 5, s, 9 and '10.)

On the lower face of the bottom plate 21 contiguous to each discharge nipple 31 of the auxiliary reservoir 22, is a solenoid 37 having a shiftable core 38. Attached to that side of the solenoid confronting the discharge nipple 31 is a depending bracket 39 provided with side-arms 40, having channel guides 11 at the lower'edges thereof. The channel guides 41 serve functionally as rails ends of shut off members 43. Each shut-off member, as best shown in Fig. 9, has yoke portions Mat the ends thereof for pivoted toggles 45, and-connected to these members by clamping bars 46, are presser blocks 47, preferably'made of yieldable material, as rubber. The shut-off members 43 are normally separated and per mit of the flexible spout 32 extending therebetween, as shown in Fig. 10, and by causing said shut-off members to move toward each other, asshown in Fig. 5, the walls of the flexible spout 32 maybe pressed or 001- lapsed to restrict the passage through the spout-or eventually shut-off the flow of ma tcrial therethrough.

The toggles 45 of the shut-off members 4-3 are pivotally connected together and 'to the lower ends of links +18 pivotally connected to c 'anks 49 on th-e end of asleeve 50, loose ona rod 51 connecting the side arms 4-0 of the bracket 39. The sleeve 50 intermediate the endsthereof, has a slotted crank 52 con nected to the core 38 of the solenoid 37, so that when the solenoid 37 is energized the toggles 45 will be broken shown in Fig. 5, thus drawing the shut-off members 43 toward each other to press or collapse walls ofthe flexible spout 32.

Pneumatic vibrators for-the auwz'liary resercoins and the oahie controlling the operation of the 'vdbrators.

(Figs. 1, 7, 12, 1e and 14.

The confronting faces of the plates 21 and ii: are connected by a plurality of pneumatic vibrators positioned between some of the spouts 32, said plates having the confronting faces thereof provided with apertured lugs 53 connected by cylinders 54 and in said cylinders are air reciprocated plungers which when actuated are adapted to vibrate the plates 21 and 34: and parts carried thereby. The pneumatic vibrators 54 are of a conventional form and are employed downwardly, as

action of the beam 74 or to.=preventthecoutents of'the auxiliar reservoir clogging the spouts 32 unbecoming caked withinthedischarge nipples 3-1. The pneumatic vibrators are connected by hose or flexible connections 55 to air pipes 56, andthese pipes extenddownwardly through the plates 3 1 to a va ve head 57fixed relaivc to the drive shaft 12. Extending into the valve head 57 and fixed on the drive shaft 12 is the hub portion 58 of a rotary member 59, said member having an annular groove 60 to receive the depending flange of a stationary semi-circular air inlet member 62, connected to an air supply pipe 63. The semi-circular member (32 has a sliding fit with the merbcr 59 and air entering said member 62 holds the member against the head 57 to preclude leakage of air. The member 62 is held against rotation by a stop 6% mounted on a three-arn'i spider 65 connecting the uprights 4c, 5 and 6. The member 62 may'receive air under compression, from any'suitable source and since such member is stationary relative to the-rotary valve-head 57, it is apparent that air it ill be alternatelyadmitted to one pipe'SG'and then to another, and in this manner the pneumatic vibrators are intermittently actuated. Rotary carrier and scale platform. (Figs. 1, 1-, 15, 16 and 1'7.)

outer marginal edges of the carrier 67 are cut away, as at 69, to provide clearance for scale platforms 70 corresponding in number to the flexible spouts 32 of themachine.

Each scale platform has a depending stirrup 71 pivotally connected as at 72, to a yoke =7 3 {on the outer end of a scale beam 74.

The yoke 73 of the scale beam 74. pivotally connected, as at 75, to a stirrup shapedhanger 760f the carrier 67 and this hanger, as well as the stirriu'), 71, has depending lugs 77 pivotally connected to the ends of a link 78. The manner of articulating the scale platform 70 relative to the carrier 67 maintains the scale platform normally in a horizontal plane duringa tilting adjustment of a poise or weight 79 on the beam.

Each scale platform has an annular depressed or counter-sunk portion 80 for a magnetic receptacle holding device 81 in the form of a coil which when rendered operativo for the purpose for which it is intended by the passing'of an electric current therethrou-gh will retain a metallic recepduring the rotary movement of the carrier.

(37, and these electrical receptacleholding devices are only brought into action durmg a portion of a revolution of the rotary carrier 67.

Pow-er distributer for the electrical devices 0] the machine.

(Figs. 1 and 18.)

On the arms of the spider 65 and insulated therefrom are brackets-S2 and 83, the latter being set in relation to the former so that the brackets may support a split distributing ring 81 concentric with a distributing ring 85 carried by the brackets 82.

On the drive shaft 12 and insulated therefrom is a distributing ring 86 supported concentric with the ring 81 and in spaced relation to the drive shaft 12 by a spider 87, said spider providing clearance for the air pipe 50 and electrical connections extending to the solenoids 87 of the machine. Engaging the distributing ring 86 is a brush 88 carried by a bracket 89 supported on and insulated from the arms of the spider 65. Connected to the bracket 89 and those brackets 82 and 83 contiguous to the bracket 89 are lead-in wires 90 from a suitable source of electrical energy, and the inner side of the distributing ring 86 has a plurality of binding posts 91 for wires 92 and 93. The wires 92 extend upwardly through the spider 6S, collar 35, plate 3 1, and through hangers 91 carried by the collar 20, to the solenoids 37. The wires 93 extend under the scale mechanism to the magnetic devices 81 in the scale platform and said devices have return wires 95 to binding posts 96 carried by and insulated from hangers 97 of the rotary carrier 67. The binding posts 96 are provided with depending resilient brushes or fingers 98 in contact with and adapted to wipe the inner side of the distributing ring 84. The gap in the distributing ring 84 breaks the electrical circuit in the magnetic devices 81 of the scale platform 70 during the interim of loading and unloading said platform.

The depending lugs 77 of the scale platform stirrups 71 are provided with insulated contact members 99, one of which is best shown in Fig. 16. Thesecontact .members are connected by wires 100 to the solenoids 37, said wires following the wire 92, as shown in Fig. 1. The contact members 99 are placed in wiping contact with the distributing ring 85 when the scale platforms 70 are depressed for the filling of receptacles, and the distributing ring 85 has an'inset portion 101 engaged by the contact members 99 after the scale platform assumes normal position. Briefly, the contact members 99 being pressed into engagement with the ring 85, establish electrical circuits through the solenoids 35 energizin said solenoids, and thus operatingthe shut-off devices. In this manner a predetermined quantity of material can be placed in a receptacle on the scale platform, but when the receptacle is removed to be replaced by an empty receptacle, it is necessary that the circuit be maintained through the electrical shut-off device until an empty receptacle is in position. This is accomplished bythe inset portion 101 of the distributing ring 85, and'as there is liable to be an are at onelend of the inset portion 101 of the ring 85, when the contact members 99 travel out of engagement therewith, an insert 102 of carbon or of material of greater resistance than the ring 85, is interposed at what may be considered the inner end of the 9 inset portion 101, as the rotary carrier 07 revolves in a clockwise direction.

Automatic loading and unloacl'z'ng device for i the rotary carrier.

(Figs. 1, 1 and 15.)

The lower portionof the platform 9 is provided with substantially a radially distending through an opening 108 in the platform and about a drum or pulley 109 mounted on a shaft 110 1ournalcd in hangere-111, carried by the bottom side of the platform 9. The outer end of the shaft 110 has a wheel 112 over which is trained a belt or. chain 113, said belt or chain extending under a wheel 114 on a radially disposed shaft 115. The radially disposed shaft 115 is journaled in suitable bearings 116 on the base 1 of the machine and the inner end of said shaft has a beveled gear wheel 117 meshing with a horizontally disposed beveled gear wheel 118 on the drive shaft 12 of the machine. The power transmission from the drive shaft 12 is such that the endless conveyer 107 will be operated at a speed consistent with the rotation of the carrier 67 so that the empty receptacles will be constantly in position to be shifted on to the scale platforms 70 of the rotary carrier.

Rotatable in the raised portion 66 of the platform 9 is a vertically disposed shaft 119 and fixed on the upper end of said shaft are sets of extensible loading arms 120 and unloading arms 121. The set of loading arms 120 is adapted to swing in a lateral plane over an adjustable stop 122 on-the platform 9 and engage an empty receptacle 123 on the conveycr 107 and shift the receptacle on to the scale platform in proximity to said conveyor. The loading arms 120 have curved extensions 124 toengage an empty receptacle following that one shifted by said arm, thus temporarily holding the following receptacle so that it cannot be shifted behind the loading arms and swept from the machine. I

The unloading arms 121 have the outer ends thereof -slightly curved so as to readily engage a loaded or filled receptacle 125 on the scale-platform 70 in th plane of the platform extension 103.

To rock the vertical shaft 119 so that the arms 120 and 121 may simultaneously load and unload the rotary carrier 67, the lower end of the shaft. 119 has a slotted crank 126, and engaging in the'slot of said crank is a pin 127 carried by one end of a lever 128 pivoted on the lower end of a bearing 129, carried by the platform 9. The lever 128 extends under the rotary carrier 67 and said carrier has a hanger 130 for an adjustable det'ent 131, which is adapted to impinge against the lever 128. Six times during each complete rotation of the carrier 67, the load ing and unloading arms 120 and 121 are actuated, and to hold said arms in position for such actuation, there is an adjustable stop 1.32 on the raised portion66 of the 131211111 form 9, said stop being engaged by the set of loading arms 120, which are held normally in engagement with the stop by the retractile force of the spring 138, below the platform and connecting the crank 126 to one of the bearings 111 of the conveyer Shaft 110.

General operation.

Although I do not show it, it is apparent that the supply of air, under compression and motive power to the machine may be simultaneously controlled, nevertheless, I will assume that the motor 16 has been started, that thedistributing rings 84, 85 and 86 are in circuit with a suitable source of elec trical energy, and that there is a supply of air, under pressure, for the air valve controlling the operation of the pneumatic vibrators.

As set forth in the beginning, the machine has been designed for filling various kinds of receptacles and as long as small quantities of matter are to be placed in receptacles it is preferable to use metallic receptacles, as cans or containers having metallic bottoms. This is essential in order that the magnetic devices may be utilized for temporarily holding the small receptacles on the scale platform,

otherwise'tlie'magnetic devicesmay be pensed with in connection with large receptacles,-as the contents thereof will'be of sufficient weight to prevent accidental displace ment of the receptacles during'the movement of the rotary carrier.

A ssui'ning that the loaded or filled receptacle has been removed from its scale platform 70, the platform is immediately elevated, taking the top of the contact member 99 out of engagement with the distributingring 85, but maintaining thesidebf the contact member 99in engagen'rent with the inset portion 101 of said distribr'iting ring. In this manner,the circuit in the solenoid above the empty scale platform n'1'ain tained closed, consequently matter cannot be discharged from the spout above the empty scale platform, during its movement from an unloading position to a loading position. I

Immediately upon anempty scale platform reaching a leading position, the set of loading arms 120 shift the empty receptacle 128 on to the empty scale platform'and this is easily accomplishedas the raised portion 66 of the platform 9'is in the same plane as the elevated scale platform. As the rotary carrier 67"is revolved, the side of the contact member 99 rides out, of engagement with the inset portion 101 of the distributing ring 85, but the top of the contact member 99 is not brought into engagement with the distributing ring 85, as the weight of the empty receptacle is not sufficient to lower the scale platform to that extent, Consequently the circuit in the solenoid above the empty receptacle is broken when the contact member 99 rides out of engagement with the inset portion 101 of the distributing ring 85. S0 matter from the auxiliary reservoir 22 may flow by gravity through the flexible spout 32 and enter the empty receptacle as it is moved by the rotary carrier 67. During its movemei'it, the weight of the receptacle increases and irrespective of its location during the cycle of the carrier 67, the moi'n'ent 4 1t overbalan'ces the poise or weight 79 of the scale beam 74 which has been previously set for a predetermined quantity in the receptacle, the contact 99 engages the distributing rin 8a and remains in contact therewith until the filled receptacle is ejected from the rotary carrier 67. Of course during this time other receptacles are being filled. The capacity, of the machine entirely depends upon the size of the rotary carrier and the loading and unloading devices serving the I same.
